While, at its core, Documents is a great way to store, manage, and view files, it also has deeper, more powerful functionality.

For example, Documents also serves as an application that allows you to annotate and search documents and PDF files.

You can also download and save documents from the web with the app. The app also allows you to easily share files with others.

In what seems to be a required feature these days, the app integrates with cloud services such as iCloud, Dropbox, and Google. This allows you to keep your contents in the cloud, and access it in an up-to-date manner on all of your iPads.
